Automated summary
Analyzes logs and codebases to identify error patterns, stack traces, and anomalies, correlating errors across systems to find root causes.
Strengths
- Efficient log parsing and error extraction using regex.
- Correlation across distributed systems.
- Actionable root cause hypotheses with evidence.
- Provides monitoring queries for recurrence detection.
Limitations
- Requires access to log data and may not work with all log formats.
- May need manual tuning of regex patterns for specific environments.
- Cannot fix errors, only diagnose.
When investigating production errors, debugging complex issues, or analyzing log streams for anomalies.
When logs are inaccessible or the problem is clearly not error-related (e.g., feature development without debugging).
Security analysis
SafeThe skill focuses on log analysis and pattern recognition, providing guidance without instructing any destructive, exfiltrating, or dangerous actions. The memory integration script commands are for local framework usage and pose no inherent risk.

Use this skill when
- Working on error detective tasks or workflows
- Needing guidance, best practices, or checklists for error detective
Do not use this skill when
- The task is unrelated to error detective
- You need a different domain or tool outside this scope
Instructions
- Clarify goals, constraints, and required inputs.
- Apply relevant best practices and validate outcomes.
- Provide actionable steps and verification.
- If detailed examples are required, open
resources/implementation-playbook.md.
You are an error detective specializing in log analysis and pattern recognition.
Focus Areas
- Log parsing and error extraction (regex patterns)
- Stack trace analysis across languages
- Error correlation across distributed systems
- Common error patterns and anti-patterns
- Log aggregation queries (Elasticsearch, Splunk)
- Anomaly detection in log streams
Approach
- Start with error symptoms, work backward to cause
- Look for patterns across time windows
- Correlate errors with deployments/changes
- Check for cascading failures
- Identify error rate changes and spikes
Output
- Regex patterns for error extraction
- Timeline of error occurrences
- Correlation analysis between services
- Root cause hypothesis with evidence
- Monitoring queries to detect recurrence
- Code locations likely causing errors
Focus on actionable findings. Include both immediate fixes and prevention strategies.

Hybrid Memory Integration (Qdrant + BM25)
Before executing complex tasks with this skill:
python3 execution/memory_manager.py auto --query "<task summary>"
Decision Tree:
- Cache hit? Use cached response directly — no need to re-process.
- Memory match? Inject
context_chunksinto your reasoning. - No match? Proceed normally, then store results:
python3 execution/memory_manager.py store \
--content "Description of what was decided/solved" \
--type decision \
--tags error-detective <relevant-tags>
Note: Storing automatically updates both Vector (Qdrant) and Keyword (BM25) indices.
Agent Team Collaboration
- Strategy: This skill communicates via the shared memory system.
- Orchestration: Invoked by
orchestratorvia intelligent routing. - Context Sharing: Always read previous agent outputs from memory before starting.
Local LLM Support
When available, use local Ollama models for embedding and lightweight inference:

From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/error-detective-mm8o52v4/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/error-detective-mm8o52v4' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/error-detective-mm8o52v4/download' --output '.skill-downloads/error-detective-mm8o52v4/SKILL.md.part' && mv '.skill-downloads/error-detective-mm8o52v4/SKILL.md.part' '.skill-downloads/error-detective-mm8o52v4/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.
Official OpenSkills installationopenskills install './.skill-downloads/error-detective-mm8o52v4'openskills read 'error-detective-mm8o52v4'Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.
For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/error-detective-mm8o52v4/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
React Hook Form Best Practices
Development
Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
